Two things are annoying me about Video Center in OS2008

1. It seems to leave temporary files all over the place, which Media Player picks up as media files, though they're not, cluttering up the Library. They seem to get deleted only when the tablet is rebooted. I can't even seem to figure out where they're being stored. Is there any way I can manually trigger whatever process cleans these up, or at least find them so I can wipe them in the terminal?

2. I used to refresh my feeds then set about 3-4 downloads going at once. It seems now that frequently as one download ends, it kills the others, leaving them as partial, requiring a click on "Resume" in the feed browser view, which invariably just begins again from 0%.

I have a feeling the files in part 1 are often the partial files from part 2. Whether this is the case or not, any ideas on no 1, and any others having the same experience as me in no 2? The garage project for VC seems pretty unused so i'm not sure about reporting a bug.
